Sarah Chalke Sports Hanes, Fights Wedgie Epidemic

This isn't the first time an underwear company has used an ass-shake to push panties. See itchy actors jiggle for Jockey.

But if watching a celeb channel Shakira doesn't do it for you, WedgieFree also includes Wedgie Stories (where you can contribute and rate tales with a blush-o-meter) and Wedgie-Free Wednesdays, a contst you can enter for free undyroos.

This is part of Hanes' effort to promote its new wedgie-free panties, which look suspiciously similar to the underpants we were forced to wear before Gwen Stefani introduced us to the subtle magic of thongs. And neckties without shirts.
